双中心双云的DMVPN设计

Design of dual center dual cloud DM VPN

针对拥有几百个分支机构的企业网络环境,其多个分支机构间需要安全可靠的通信,采用DM VPN这个高扩展性的IPSec VPN解决方案,部署VPN隧道加密企业网络通信.DM VPN技术可以直接将分支机构的通信加密,不需要经过中心机构的转发,为中小型企业网络的互联节省了成本,在提高网络的可用性与安全性的同时也使得应用和管理更加简易.

In an enterprise network,usually there are hundreds of branches,all of which need secure and reliable communications.As a highly scalable IPSec VPN solution under the network circumstance,DM VPN is used to de？ploylarge？scale VPN tunnel to encrypt the communication between corporate network branches. The proposed dual center dual cloud DM VPN directlyencrypts the communication in the branch networkwithout the forward process by the network center,which canreduce the cost and improves the networksecurity for medium or small scale enterpri？ses.
